The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6g, M13 x 0.5 – is a precision limit gauge used to verify external threads on metric fasteners. Specifically designed for NoGo testing, it helps you quickly confirm whether a part’s diameter stays within the allowable maximum for M13 x 0.5 right‑hand threads. It’s a practical tool for engineers, machinists, inspectors, and quality teams across manufacturing, automotive, and maintenance environments.

Crafted from hardened steel for lasting durability, this ring gauge maintains tight dimensional control and resists wear through daily shop use. The precision-machined surfaces and the knurled outer edge, visible in the product image, provide secure grip for easy handling and repeatable checks in busy inspection pockets.

• Fast NoGo verification for M13 x 0.5 right-hand threads: Quickly determines if the external thread diameter exceeds the maximum, enabling rapid acceptance or rejection of parts in QA workflows.
• Rugged, hardened steel construction: Built to withstand demanding environments and frequent use without losing accuracy or shape.
• Precise, repeatable dimensions: Meticulous machining ensures consistent results across inspections and operators, helping maintain uniform quality.

Using this gauge streamlines your inspection routine, reduces downtime from uncertain measurements, and strengthens conformity to thread standards. Its durable build and clear NoGo indication support confident decisions in production, assembly, and service tasks, delivering reliable performance over the long term.
